-T0-aZZ whom, it may concern/.

the following is a full, clear, and exact description.

. This invention has more particularly for its object the manufacture oflamp or carbon black from crude petroleum and thick oil or sedimentcommonly known'as black stuff,

which is the refuse of petroleum-tanks, also from the acid waste ofpetroleum-refineries.

The invention consists in certain combinations of devices in anapparatus for making carbon-black from liquid fuel, as above described,and in which said fuel is supplied under pressure to burners chargedwith asbestus or other incombustible material, substantially ashereinafter described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in-

which similar letters of reference indicate corresponding pagts in allthe figures.

Figure 1 represents a partly-sectional ver tical view of an apparatusembodying my invention; and Figs. 2 and 3, partly-sectional views, upona larger scale, of certain details.

A indicates an elevated tank containing the oil or fluid substance to beburned, and which may consist of a given amount of black stuff or acidpetroleum waste,with a sufficient amount of benzine added to make thewhole of the requisite fluid consistency. The liquid fuel is drawn fromsaid tank by means of a siphon, B, for delivery under pressure to theburners, that, by reason of their construction, require a certainpressure to supply them. Said burners consist each of a cup, 0, filledwith loose asbestus or mineral wool, 72. Any number of these burners aremounted by small tubes 0 upon a horizontal pipe, I), which is suppliedwith liquid fuel fromflthe tank A by the siphon B, and aconnecting-pipe, cl, subject to control by a regulating or shutoff cock,0.

E E are a series of sheet-iron or other thin cones of suitabledimensions to receive within them from beneath one or more of the burn:ers C. These cones are arranged slightly inclining, apex upward, and sothat their upper surfaces are not greatly removed from a horizontalposition. andtheir bases or open lower ends are at right angles, orthereabout, to the longitudinal axes of the cones. The apex of each coneis closed and secured to a rod or shaft, f. These shafts are journaledon posts 9, and revolved bybevel or friction gearing h h from a power orcounter shaft, F. The rim of eachconeE, at its base, is turned outward,or madeto form a projecting'd'eflector, flange, or curb, 7c, the purposeof which will be hereinafter described.

From a pipe, Z, overhead, cold water is supplied by-dip-pipes Z to theouter and upper surface of the cones, said dip-pipes being suitably bentand perforated at their lower parts, to lie parallel with and close tothe upper inclined surfaces of the cones, and to distribute over thesamethe cold water which issues from said pipes. The tubes 0 are'so bentorinclined as that the flames from the burners C will play directly uponthe interior of the upper sides of the cones opposite the distributingbent lower portions of the pipes Z. In this way the flames strike thecoldest portions of the 1 cones, which causes the fumes to be condensed.The cold water, thus striking the cones immediately'over the flames'ofthe burners, naturally gravitates toward the base ends of the cones,

and, coming in contact with the flanges or curbs k of the cones, isdeflected into atrough, G, running along under the cones, and thencecarried away.

Directly under the cones, in front of the water-trough, are funnels m,to receive the carbon produced by condensation of the fumes asit isremoved from the interior of the cones. These funnels m have attached tothem steel scrapers H, which extend up within the cones on the sidesthereof opposite to the sides on which the flames of the burners play.

The operation is as follows: As the cones E are rotated, thecarbon-black formed upon their inner surfaces is detached by thescrapers H, and by the directions assumed by the base ends of the conesreadily falls into the funnels m and passes into a trough or tube, I,from which it may be removed by an elevator or any other suitable means.

In an apparatus of this description the greatest facility is affordedfor increasing or de creasing its working capacity to suit a variabledemand or different requirements. Thusin an apparatus made up of a largenumber of rotating cones and burners the same may be worked inindependent sets of, say, three or four in each setthat is, the burnersof each three or four of the cones may be supplied with the liquid fuelby a separate branch from the main supply-pipe and be controlled by aseparate cock, s. This provides for the supply being cut off fromcertain of the burners without shutting it off from the others. Thegearing also by which the cones are rotated can be so arranged that anysingle cone or series of cones can be disconnected without affecting theothers. The oil or liquid fuel, being under hydrostatic pressure, issuitably supplied to the burners and caused to saturate the asbestuswith which the cups of the burners are filled, and which forms theburnersurface. The asbestus, being incombustible, can readily berecleaned, when clogged with oil or soot,by exposing it to the action offire. Furthermore, the cold-water perforated distributing-pipes,arranged in relation with the cones and their burners as described,effect a perfect and rapid condensation of the carbon within the cones,and as the cones are rotated the flame and heat of the burners areconstantly presented to a bright orclean conesurface by reason of theaction of the scrapers on the rotating cones, and whereby the carbondeposited on the interior of the cones is prevented from being consumedor injured by the flame and heat of the burners.

The invention is not necessarily restricted, so far as the process inconnection with the cones and other apparatus are concerned, to the useof petroleum as a fuel in a strictly liquid condition, inasmuch as thenatural Vapor of petroleum, or natural gas, as it is termed, might beused.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In apparatus for the manufacture of lamp or carbonblack, thecombination, with one ormore rotating devices for the collection of theblack upon the surface or surfaces thereof, of one or more cup-shapedburners packed with asbestus, mineral wool, or other like incombustiblematerial, and devices for supplying the fuel under pressure to theburner or burners, substantially as specified.

2. In an apparatus for manufacturing carbon-black, the combination ofthe rotating hollow cones E,made open at their bases, and arranged foroperation as described, and of burners within said cones, arranged toproject their flames against the upper sides of the cones, with ducts orpipes arranged to distribute cold or cooling water over the upper sidesof the cones, 011 the exterior thereof, and in relation with theburners, essentially as and for the purposes herein set forth.

3. In an apparatus for manufacturing carbon-black, the combination ofthe rotating hollow cones E, arranged for operation as described, andhaving deflecting flanges or curbs 7c around their open bases,theperforated coldwater-distributing pipes Z, andthe burners C,substantially as shown and described.

4. In an apparatus for manufacturing carbon-black, the combination ofthe stationary scrapers H with the rotating hollow cones E and theburners 0, arranged for operation in relation with each otheressentially as and for the purposes specified.

5. 1m an apparatus for manufacturing carbon-black, the combination ofthe elevated tank A, the siphon B, the pipes d D, the burners G, and therotating hollow cones E, substantially as described.
